The "Influence" model has nickel silver, flute like, key touches rather than the standard abalone touches. These keys translate into what feels like faster action and ease of play in your hands. I didn't believe this was possible until I played it and it does give the perception of increased speed to your fingers!!! Finish is antique/vintage Dark Lacquer (DK) or Un-lacquered (UL). A strong alto for a strong player.
